Ingredients

Scale

For the Garlic Preparation:

  • 1 large garlic bulb, peeled and sliced
  • Olive oil for drizzling (part of 2/3 cup total)

For the Soup Base:

  • 1 tbsp dried sage (or 3 tbsp fresh chopped sage)
  • Pinch of salt
  • 64 oz chicken stock (can substitute vegetable or beef stock)

For the Emulsion:

  • 2/3 cup extra virgin olive oil (divided: some for roasting and remaining for emulsion)
  • 1 tbsp Dijon mustard
  • 1 egg yolk, at room temperature

Instructions

  1. Roast the Garlic: Preheat your oven to 400°F (200°C). Spread the sliced garlic bulb evenly on a baking tray and drizzle lightly with a bit of olive oil. Roast for 30-40 minutes until the garlic becomes soft and golden, which develops its sweet and mellow flavor.
  2. Prepare the Chicken Stock: While the garlic roasts, pour the chicken stock into a large pot and bring it to a gentle boil over medium-high heat. Once boiling, add the dried sage and a pinch of salt. Lower the heat to a simmer to maintain warmth without boiling vigorously.
  3. Mash the Roasted Garlic: Remove the roasted garlic from the oven and when still warm, mash it into a smooth paste using a fork. Warm garlic mashes more easily and integrates better into the soup.
  4. Make the Emulsified Mixture: In a small bowl, whisk together the egg yolk and Dijon mustard until smooth. Slowly drizzle in the remaining olive oil while whisking continuously to form a creamy, stable emulsion similar to aioli.
  5. Combine and Serve: Stir the mashed roasted garlic and egg-mustard-olive oil emulsion into the hot chicken stock. Whisk well to combine thoroughly. Serve the soup warm, optionally accompanied by roasted slices of baguette for dipping.

Notes

  • Do not add the egg yolk mixture directly into boiling stock to avoid scrambling; temper it first by whisking in warm stock gradually.
  • Keep heat medium-low when roasting garlic to prevent burning and bitterness.
  • Add olive oil slowly and whisk vigorously when making the emulsion to keep it smooth and creamy.
  • Strain the soup for a silky texture if desired.
  • Serve warm, not piping hot, to preserve delicate flavors.
  • Store soup in an airtight container in the refrigerator for up to 4 days; avoid freezing due to the egg and oil emulsion.
  • Reheat gently over low heat and stir often to prevent egg from scrambling.
